mless: doesn't work on OpenBSD 7.6 due to lack of LESSOPEN

[leahneukirchen]

LESSOPEN support was removed in OpenBSD in openbsd/src@c74702f

I'm not sure how we can have something like mless without this feature... one would need to pre-render the whole sequence perhaps?

That might result in performance problems for large sequences. I've just gotten around it by piping a message with the preamble into less, though that doesn't allow me to page through mail, but oh well.

One approach could be to drive less in a loop, and use exit codes to switch between files, only starting less with one mail rendered every time.
